GRAIN SCOURING AND CLEANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 325,919, dated September 8, '1885,

Application filed April 8, 1885.

To @ZZ whom it may concern.-

Be it knownthat I, AUGUSTUS G. DEoBoLD, of Bloomingtomin the county of McLean, and in the State of Illinois, have invented certain new and useful Improvements in Grain Scouring and Cleaning Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the let-V ters of reference marked thereon, making a part of this specification.

My invention relates to a machine for scour` ing and cleaning wheat, grain, and like substances; and it consists, substantially, in the parts as constructed, and in the particular combinations thereof, to be hereinafter distinctly described,and pointed outin the claims. The object of my invention is to furnish a machine for scouring and cleaning grain, that is comparatively inexpensive in the cost of manufacture, and one possessing great simplicity, ease of operation, and thorough effectiveness in the results to be accomplished.

Reference being had to the accompanying sheets of drawings, Figure 1 represents' a sectional elevation,on line y y, Fig. 2,0fa machine embodying my invention. Fig. 2 represents a front sectional elevation thereof 0n the line w x. Fig. l3 represents a perspective view of the revolving cylinder and its casing,both being partly broken away to more clearly indicate their construction. Fig. 4 is a sectional end view of the cylinder and its casing, being broken off at each end and showing the manner in which the same are constructed. Fig. 5 is a detail View showing the manner of constructing the casing and its inclosed cylinder. Reference being had to the several parts by the letters marked thereon, A represents a structure comprising the machine proper, the same being of any suitable frame-work so united or put together as, to form an upper chamber, c, in which is borne and revolves a fan, b, a suction spout or fine, c, communicat-V ing at its lower end with the external air,and the casing discharge-spout, through which latter a current of air is caused to pass upward by the action of the fan, carryingtherewith the chaff or beards from the grain,that is discharged from the cylinder-casing into said flue at the bottom adischarge-hopper, d, located at the upper extremity of ue @and communi- (No model.)

eating therewith; a valve, e, arranged intermediate of said hopper and suction-Hue, for regulating the current of air passing through the latter, and an additional spout or iiue, f, leading upward from an opening in one of the casing-heads, through which` the dust or extremely-light particles are carried from between the cylinder and its casing during the scouring action` to which the grain or other substance is subjected during its passage therethroughsaid dust being carried 'off or discharged as indicated by the arrows.

Beneath the fan is located a stationary cylindrical casing, C, having an inlet spout'or opening, g, through which the grain or other substance is fed. This casing is constructed of two heads, c c', in the center of one of which is an opening, d', communicating with flue f, as shown. Said heads are formed with perforated radial lugs e', and are provided at their edges with inner circumferential flanges or beading l 2. y Between the heads is held a cylindrical shell, the edgesof which fit bctween the flanges l 2, and whose inner surface is formed or provided with ribs orcorrugations i, Fig. 4, extending from end `to end thereof in an oblique direction and approximately forming a spiral around the shell in the direction of its length. The manner of securing the shell h between the heads c c' is -by rodsj fitting in the lugs e and tightened or secured in any suitable manner.

Vithin the shell a cylinder, D, revolves, the saine being mounted orsupported upon ashaft, 7c, extending between the sides of the machine in suitable bearings, as shown. This shell is constructed in like manner as its casing-z'. e., of two heads, Z Z, formed with inner flanges, 3 4, the said heads securing between them acylindric shell, n, to the outer surface of which is secured,by screws o o,a series of ribs, p, arranged in a similar direction to those on the inner surface of the casing. Motion is imparted to the apparatus by means of any suitable power connecting with ,the pulley r on shaft 7c, from whence it is communicated by means o f pulleys s s to the shaft t by which the fan is revolved.

'Ihe nature of the general construction of my amachinewill be u nderstood from the foregoing,

and I will now proceed to describe the operation.

vIO

The grain, wheat, or other substance is fed between the revolving cylinder' and its stationary casing through the opening g in the latter. During the scouring and rubbing of the grain between the ribs on the opposite surfaces of the two, the fan causes a suction up through the iiue f, and by which the dust or extremely-light particles are carried out. The substance is finally discharged through spout u into the bottom of the flue c, and there it is niet by the suction of air in said iiue, the iine or extraneous particles being carried upward and discharged throughv hopper d, while the heavier are deposited in a heap to be gathered or collected. The valve e can be operated to regulate the current of air in spout c, and at thebottom of the hopper is provided a iiapvalve, M, which is for the purpose of preventing the passage of external air into the hopper, and which also is of sufficient flexibility to allow the chaff or screenings to fall th rough of their weight.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent- 1. A grain scouring and cleaning machine comprising the revolving cylinder and its casing, each being constructed of a cylindric shell whose contiguous surfaces are provided with series of oblique ribs secured by screws, and twoheads having inner ianges or beads, the two airflues, the revolving fan, the valve for regulating one of said dues, and a hopper into which the extraneous substances are received, the said hopper having at its lowerend a. fiexble valve, all substantially as described.

2. In agrain scouring and cleaning machine, the combination of the revolving cylinder and its stationary casing, each being constructed of two heads having inner flanges or beads, and a cylindric shell held between such heads, having on their contiguous surfaces series of oblique ribs 'secured thereto by screws, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand, this 28th day of 45 February, 1885.
